IPC: E02D3/12
Filed: 1981-12-16
Abstract: PURPOSE:To simplify the structure of a grout injection system by a method in which each liquid of a two-component curable grout is sent to the first flowpath in an outer tube and the second flowpath with a spool valve in an inner tube, joined in an annular mixing chamber, and then injected into the surrounding ground while being mixed. CONSTITUTION:A first flowpath P1 is formed between outer tubes 22A-22C of a tip device 6 connected to an injection tube body 4 and an inner tube 26, and also a second flowpath P2 is formed in the inner tube 26. When excavating a hole underground, boring is made by jetting a boring water W from a nozzle 10 through a check valve 28, the first flowpath p1, the spool valve 42, and a check valve 36. Also, when improving the ground, the first liquid G1 is sent under pressure to the first flowpath P1 and the second liquid G2 is sent to the second flowpath P2, whereupon the spool valve 42 is pushed down by the second liquid G2 and the liquid G2 is discharged from a discharge port 46 and at the same time a shutter 42B is moved downwards from an injection port 12 to form an annular mixing chamber 48.

Title: Molecular beam epitaxy equipment
Inventor: OOTA TOSHIMICHI
IPC: H01L21/26
Filed: 1986-08-29
Abstract: PURPOSE:To preferably grow a crystal by using a graphite oriented on its c-axis perpendicular to its surface and a laminated plate of boron nitride of hexagonal crystal oriented on its c-axis parpendicular to its surface on both side surfaces of the graphite as a susceptor. CONSTITUTION:Boron nitrides 2 of hexagonal system crystal formed by a thermochemically depositing method by a reaction of boron trichloride with ammonia at a high temperature under a reduced pressure and oriented on its c-axis perpendicular to its surface are laminated, for example, on both side surfaces of a graphite 1 oriented on its c-axis perpendicular to its surface. Both the graphite 1 and the nitride 2 have much higher thermal conductivity in the surface direction than that in the perpendicular direction. Accordingly, uniform thermal distribution is easily obtained in the surface direction, and heat is scarcely dissipated from its periphery. Both the surfaces are so covered with the boron nitrides so as not to affect the growing substnace to the minimum possible. Thus, it can prevent the quality of the film from being deteriorated to preferably grow the crystal.
